APPARATUS FOR MAKING RIVET-CLOTH.

Specification of Letters Patent.

Patented Ane'. 26,1913.

Application filed November 20, 1912. Serial No. 732,427.

To @ZZ whom t may concern:

Be it known that l, .limosna T. RU'rLnnGn, a citizen of the United States, residing at Millbury, in the county of Viforcester and State of Massachusetts, have invented a new and useful Apparatus for Making Rivet-Cloth, of which the 'following is a specification.

rThis invention relates to the n'lanufacturc of a cloth Without pile having when produced on the loom, perforations therethrough arranged at intervals both longitudinally and across the goods.

The principal type of fabric to which this invention relates is the so-called rive cloth which is used in the manufacture of rubber tires, but it is capable of use for the production of any such fabric.

The invention involves certain features of the machine by Which7 after a definite amount of filling has been Woven in, the loom will be stopped in order to permit the insertion of a rod to form the space between the tivo sections of filling; the provision o f means whereby the rods are automatically7 drawn out of the cloth and discharged in convenient position for reuse; the provision of means for trimming off extending threads on one side of the fabric; and other features of construction as will appear hereinafter.

Reference is to be had to the accompanying drawings7 in Which- Figure 1 is a plan of a portion of a loom constructed in accordance with this invention showing how rivet cloth can be made thereon; Fig. 2 is a front elevation of the same showing the means for renioving the rods; Fig. 3 is a similar view showing the opposite end of the rod removing means; Fig. 4 is a plan of a portion thereof on enlarged scale; Fig. 5 is a perspective view of a detail thereof; and Fig. 6 is an end view of the loom showing the automatic stopping means.

Se far as I am aware rivet cloth has been manufactured heretofore by Weaving a continuous length of cloth and having the filling inserted continuously from end to end of a continuous Warp, but the Warp and filling in the places Where the openings are to appear are of a different colo-r from the main body of the fabric, and after the fabric is Woven they are drawn out. This is an expensive method, involving' not only a slight complication in the Weaving, but especially taking considerable time in the drawing out of the colored threads, and the Wasting of these threads. This invention designed chiefly to avoid this Waste by making the fabric originally with the openings therein, so that the threads Will not have to be cut and drawn out, or at least only two will for each space, and also to provide simple means for cutting and freeing the threads which are drawn out in order to leave only a firm fabric.

Referring now to the drawings7 a loom is shown having the usual crank shaft 10, lay 1Q, breast-beam 13, temples 14e, harnesses 15, jacks 1G7 and shipper' handle 17. The connections of these parts are not shown herein in full as they are well-known in this art and any ordinary or desired types of these parts can be employed with this in vention.

For t-he purpose of producing the rivet cloth or other fabric of a similar nature in a cheap and expeditious manner, the following arrangement is provided. First, the Warp A is arranged to consist of a plurality of sections of main Warp threads a arranged in a plurality of series of a given number of threads each, say for example eight. These threads are separated by spaces substantially of the same Width as the Width of a section of these Warp threads. Outside the main Warp are tivo Warp threads a2, the purpose of Which Will be described hereinafter.

The filling is Woven into these varps in the usual manner the usual roller chain (not shown) being employed to operate the j acls7 but one of the jacks 16 Which operates only after a denite number of picks are made, as for example ten, is provided with a connection 20 which passes around rollers i@ on the frame, and is connected with the shipper handle 17. Thus the connection 2O is arranged so as to be actuated at regular intervals, as for example, at every tenth pien in the embodiment illustrated in the drawings. ln other Words when ten picks of filling have been inserted in the Warp, the connection 2O will be actuated. to move the shipper handle and thus stop the loom. Then the operator inserts a rod into the Warp as indicated in Figs. 1 and 2. Each of these rods has a hook 2G on one end.

Connected With the main or crank-shaft 1 0 is a transverse shaft 27 provided with a sprocket wheel 28. Over this sprocket wheel and another sprocket wheel 29 passes an endless chain 30 having one or more projections 3l thereon in position to engage a hook 2G of one of the rods 25 at regular intervals during the operation of the loom. These parts obviously are so timed that as the cloth feeds over the breast beam the projections 3l will come into engagementwith the respective hooks 26 when these hooks reach a predetermined point.. In this case then these members will operate once for every ten picks. The rotation of the shaft 27 and the movement of the chain 30 in the direction indicated by the arrow in Fig. 3 draws out each rod 25 until it comes against one of the bell cranks 33. These bell-cranks are provided with springs 34e for holding them normally in position to be engaged by the end of the rod as the same travels along. This swings the bell-crank back until the end of the rod slips over the inclined edge 32. The further travel of the rod forces it up the inclines 32 as the bell crank swings back and the rod therefore is raised above the top of the pins 31 and discharged from the chain into a receptacle as 35 or the like. In this way the rods are prevented from engaging the chain.

Referring especially to Fig. l, it will be seen that the filling is woven into the fabric to form the usual filling strand across the same, but that just before the loom stops, that is on the ninth pick in this case, a loop is formed on one side of the fabric around the side warp thread a2. It is then woven into the fabric and extends out on the other side at b2 around the other strand a2. Then it passes to the other side of the rod 25 which has been inserted and is woven in again forming a second loop on the other side. It then continues to be woven in for the desired number of picks, for example, ten, when the loom again stops and the next rod 25 is inserted. It will be understood, of course, that these rods 25 can be inserted by the means which are employed for introducing pile wires in carpets, on carpet looms and the like, without departing from the scope of the invention as expressed in certain of the claims and in fact so far as the method is concerned can be bot-h inserted and withdrawn by hand. Now as t-he fabric passes on, and preferably before the rods 25 are withdrawn, it is caused to come int-o contact with a. fixed or adjustable blade 40 at one side. This blade is located directly at the edge of the main warp so as to sever the loops of the filling.

For the purpose of insuring that the filling actually remaining in the fabric shall be firmly woven therein and not likely to spread out in the rectangular spaces to be left, an extra filling thread iS left on each side of each space. These are the ones which are now connected with the strands Z22 and as their opposite ends are clipped it will be obvious that each pair of them can be drawn out simultaneously with great rapidity and without interfering with the strength and firmness of the fabric. In this way the expensive operation of clipping and pulling out by hand all the threads to form spaces in the cloth is, for practical purposes, eliminated and this reduces the cost of the material very essentially. Gn accountof having the end strand that comes next to the rod drawn out the filling that remains is firm, secure and uniform. In this way this kind of fabric is inexpensively manufactured and is made uniform throughout as the hand operations are dispensed with. At the same time a fabric is secured which is an improvement over the old handdrawn rivet cloth in the particulars above specified.

Although I have illust-rated and described only a single embodiment of the invention I am aware of the fact that modifications can be made therein -by any person skilled in the art'without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but

What I do claim is l. In a loom, the combination with a lay, breast-beam, shifting handle, and jacks, of means connected with said jacks for moving said shifting'handle to stop the loom after a definite number of picks, so that a rod can be inserted in the warp before the loom is again started, and means for automatically withdrawing said rods.

2. In a loom, the combination with a lay.` breast-beam, shifting handle, and'jacks, of means connected with said jacks for moving saidV shifting handle to stop the loom after a definite number of picks, so that a rod can be inserted in the warp before the loom is again started, and means for automatically withdrawing said rods, said means comprising an endless chain provided with a projection for engaging the rod and pulling it out from the side of the fabric.

3. In a loom, the combination of means for holding the warp, and means for inserting the filling therein, with means for stopping the loom at regular intervals in order that a rod may be inserted in the warp after each stop, means for withdrawing said rods from the fabric, and means for engaging said rods and detaching them from the rod withdrawing means.

4. In a loom, the combination with the breast beam, of an endless chain arranged to move adjacent thereto, means for operating the endless chain, the endless chain having a projection for engaging a rod in the fabric and drawing the rod ont from the side of the fabric, and means adjacent to the endless chain for throwing the rods therefrom.

5. In a loom, the combination of a shaft, a sprocket wheel on the shaft, an endless chain connected with said sprocket wheel, a projection on the chain for engaging a rod and drawing it ont of the cloth woven on the loom, a lever arranged in the path of said rod as the chain travels, said lever hav- :ing a slanting surface for engaging the rod and lifting it from said projection.

6. In a loom, the combination with the breast beam of an endless chain adjacent thereto having a projection thereon for engaging a rod in the fabric, means for moving the chain, and a member having a slanting surface in the path of the rod as it moves .along with the chain for forcing the rod up from the projection and disconnecting it from the chain.

7. In a loom, the combination with the loom frame of an endless chain having a projection thereon for engaging a rod in the fabric on the loom, and means for disconnecting the rod from said projection, comprising a member having a slanting surface in the path of the rod as it moves along with the chain for forcing the rod up from the projection, and yielding means for holding said slanting surface in position.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
